Özet

Orius laevigatus (Fieber 1860) (Hemiptera: Anthocoridae) is a commercially used predator against soft-bodied pests in greenhouses. Many researchers have done studies on oviposition preference and hatching rate of O. laevigatus which are essential components for the mass-rearing studies of biocontrol agents. In addition, the effects of succulent plants and their potential to use for mass-rearing of O. laevigatus have not fully examined. This study has been done to determine the most suitable host plant for the oviposition preference of O. laevigatus at laboratory conditons between the year 2021 and 2022. No-choice and choice experiments were conducted for the five different succulent plants (Sedum nussbaumerianum Bitter, Kalanchoe daigremontiana Raym.-Hamet & H.Perrier, Kalanchoe blossfeldiana Poelln. (Saxifragales: Crassulaceae), Senecio barbertonicus Klatt. (Asterales: Asteraceae) and Aptenia cordifolia (L.f.) N.E.Br. (Caryophyllales: Aizoaceae) at 25ºC ± 2. %65 ± 10 relative humidity, and 16:8 L: D in climate rooms; According to the results of the No-choice experiment, Kalonchoe blossfeldiana, A. cordifolia, and S. barbertonicus were found the most successful host plant in terms of daily (5.14 ± 0.33, 6.73 ± 0.43, 6.19 ± 0.43) and total laid eggs (74.24 ± 5.70, 61.64 ± 4.51, 84.67 ± 5.50) and hatching ratio (75.01 ± 3.45, 74.40 ± 2.06, 64.26 ± 3.00). Out of these three host plants used for the choice experiment, Kalonchoe blossfeldiana was determined as the most suitable host plant in terms of daily and total laid eggs (3.42 ± 0.38, 33.28 ± 3.98), and hatching rate (22 72.40 ± 2.80 per cent). Consequently, K. blossfeldiana was found to be the most suitable host plant in terms of oviposition and hatching performance for the mas-rearing of O. laevigatus.
